The air quality trends presented in the 2001 California Almanac of Emissions and Air Quality represent a summary
of data collected at a number of monitoring sites. Whenever data are summarized, the results can be influenced
by many factors, including the number monitoring sites in the network, the opening and closing of critical sites,
and the completeness of the data. The following document, updated during December 1998, provides information that
